Aircraft engines are normally designated by obscure numbers only an engineer could love but as a clear expression of market intent, GE is giving its new turboprop engine a name: the GE Catalyst Advanced Turboprop engine. (Heretofore, it was simply the ATP engine.) GE announced the new engine in 2015 and last fall, it reported […]

When AVweb visited the Cirrus factory last summer, it was in the process of reorganizing to ramp up production of the new Cirrus SF50 VisionJet. In this detailed video, AVweb’s Paul Bertorelli reports on how the factory builds its popular piston and jet aircraft. view on YouTube

With the new ATP engine still in development, GE continues to market its line of H80 turboprop engines meant to compete with Pratt & Whitney’s PT6. GE’s Matt Garas gave AVweb a tour of the new engines at the NBAA show in Last Vegas in 2015. view on YouTube

Rotax is about ready to roll out its new 915 iS engine and it will soon be available in uncertified form as a powerplant choice for experimental amateur built aircraft and high-performance LSAs.

A piece of aviation history roared to life for the first time in a decade last week in an important milestone toward first flight. Crews at Basler Turbo Conversions in Oshkosh started the No. 1 engine in That’s All Brother, the C-47 that led 800 other aircraft in the invasion of Normandy on D-Day. The […]

Two years ago, GE’s Business and General Aviation group announced a clean-sheet engine called the Advanced Turboprop or ATP. The engine will run later this year and GE is already building the manufacturing technology. In this AVweb video shot at NBAA-BACE 2017, GE’s Paul Corkery explains how many of the engine’s major components will be […]

The idea of stuffing more air into an engine to increase its power output is anything but new. Mechanically driven superchargers have been compressing ambient air and feeding it to engines since at least 1885, with their exhaust gas-driven offspring, turbosuperchargers (often shortened to turbocharger or turbo), since 1905. The first turbos were installed in […]
